ABOUT
----------------------------------------------------------------------------------------------------------------

The Seminar on Ontology Research in Brazil (ONTOBRAS) is a scientific venue for researchers and practitioners from computer and information science to discuss theories, methodologies, languages, tools, and experiences related to the theory and practice of ontologies. In addition, Master's and Ph.D. students whose research is focused on Ontologies will find in the Doctoral and Masters Consortium on Ontologies (WTDO) the opportunity to present and discuss their proposals with experts in the field – a valuable opportunity to receive feedback on their research and network within the community. Likewise, through the Tutorials Track. Students, practitioners, and lecturers will have the opportunity to learn techniques and tools used by the community.

In its 15th edition, ONTOBRAS 2022 is recognized by the Brazilian ontology community as a unique and highly qualified forum for the presentation and discussion of ontologies and application cases in Brazil. The WTDO is in its 6th edition and has been consolidating itself as a rich space for discussion among researchers of different generations, contributing to the expansion and renewal of the community of ontology researchers in Brazil. This year, with the tutorials track, participants will also have the opportunity to learn state-of-the-art ontology techniques and tools.

TOPICS
----------------------------------------------------------------------------------------------------------------

We list in a non-exhaustive way areas and research communities from which we expect to receive submissions:
- Conceptual modeling: conceptual methods and tools for the formal representation of concepts in ontologies.
- Information Science: construction and use of taxonomies, thesauri, knowledge organization systems, information indexing, and other applications.
- Logic and Reasoning: formal representation languages and systems applied to representation and reasoning with ontologies.
- Philosophy: philosophical aspects that underlie ontological modeling, top ontologies, mereology, essence and identity, and others.
- Software engineering: ontology representation languages, system architecture, methodologies for developing ontology-based systems.
- Linguistics and natural language processing: concept extraction, meaning determination.

Researchers and practitioners are invited to submit theoretical, technical, and practical research contributions that directly or indirectly deal with the areas listed above. We welcome papers ranging from philosophical and theoretical foundations to new technologies and innovative applications.
